Miniature field testing shows alpine PV array performs better than expected
Researchers have constructed a miniature PV field at an altitude of 2,500 m in Switzerland. They tested it across 80 different positioning settings and compared the results to the guidelines provided by the Swiss government for a subsidy program. They found that the simulated yield was underestimated by up to 16%.
Swiss startup offers demand side management software to manage energy flows
Swiss-based Hive Power has launched Flexo to optimize grid-connected devices, enabling flexibility in markets with dynamic tariffs. The Flexo solution has interfaces to integrate inverters, home energy management systems, charging point managements systems, meters, and other internet of things (IoT) devices.
Researchers develop high transparency nanocellulose film for photovoltaics, packaging
The nanocellulose film can be used for light management as its light scattering is adjustable. It also exhibits a transmittance of over 80% at 550 nm.
How to achieve higher power yield in east-west oriented solar arrays deployed on flat roofs
Researchers in Switzerland investigated different setups to maximize energy yields per area for PV Systems on flat roofs. Their work revealed that using horizontal single-axis tracking and reflectors could add up to 5% greater performance.
Perovskite-HJT tandem solar cell based on phosphonic acid, self-assembled monolayer achieves 30.22% efficiency
Researchers in Switzerland have fabricated a perovskite-silicon tandem solar cells that utilizes a heterojunction cell as bottom device. The cell is said to circumvent the film formation issue associated with the use of phosphonic acid and achieve high efficiency levels.
The Hydrogen Stream: IGI Poseidon, Corinth Pipeworks test H2 transport pipes
IGI Poseidon has partnered with Corinth Pipeworks to test carbon-steel pipes for hydrogen transport under high pressure, while Axpo has begun building a green hydrogen plant in Switzerland to fuel vessels and other applications from 2026.
Researchers complete Europe’s first PV soiling loss assessment
A European research group has adapted a soiling model for use across the continent, analyzing scenarios with complete and partial rain cleaning to calculate energy losses and increases in the levelized cost of energy (LCOE), marking Europe’s first techno-economic PV soiling assessment.
Swiss utility to support more targeted use of solar power with dynamic tariff
Swiss energy company CKW says its new tariff, which will calculate prices according to kilowatts, rather than just kilowatt-hours, will incentivize more targeted use of solar power during the day.
Swiss startup offers wavelength-selective PV system for agrivoltaics
Voltiris has launched its latest greenhouse pilot project, installing its novel wavelength-selective PV system at a vegetable growing farm in Canton Baselland.
Screen-printed colored glass BIPV modules with sequins-like effect
Swiss retailer Lehner Versand generates 24.5% of its building energy needs thanks to a renovation project that added 109 kW capacity of solar PV to its facade. The PV array has a sequins-like effect, enabled by screen-printed glass modules and a novel curtain wall sub-structure.
